Jerry Cwiklik reopened UIMA-5157:
---------------------------------
When agent receives SIGTERM, the child processes are still not cleaned up.
> DUCC shutdown sequence leaves agents running
> --------------------------------------------
>
> Key: UIMA-5157
> URL: https://issues.apache.org/jira/browse/UIMA-5157
> Project: UIMA
> Issue Type: Bug
> Components: DUCC
> Reporter: Eddie Epstein
> Assignee: Jerry Cwiklik
> Fix For: 2.2.0-Ducc
>
>
> A full DUCC shutdown (./stop_ducc -a) can leave DUCC agents as well as user
> processes still running after shutdown completes.
> The problems are caused because 1) a DUCC agent will hang trying to send
> inventory update report if the DUCC broker has been terminated, and 2) agents
> kill user processes sequentially which increases the likelihood that the
> broker will be terminated before the agent is finished cleaning up.
